A cell phone provider offers a plan that costs $20 per month plus $0.20 per text message sent or received. A comparable plan costs
$30 per month but offers unlimited text messaging. Complete parts a. and b. below.
a. How many text messages would have to be sent or received in order for the plans to cost the same each month?
In order for the plans to cost the same.
text messages would have to be sent or received
b. If you send or receive an average of 200 text messages each month which plan would you choose and why?
Answer:
Step-by-step explanation:
a)
30=20+0.2m
10=0.2m
50=m
So after sending 20 messages the plans would cost the same.
b)
Obviously from the first part that the unlimited plan is cheaper when sending 200 messages, but the costs numerically would be.
Unlimited plan costs $30 while the other plan costs
20+0.2(200)=$60

Rachel has been given $1000 to put into a savings account. She earns 2% simple interest
every month. Rachel hopes to buy a car in two years. Help Rachel determine whether she
will have enough money if the car will cost $1500.
Answer:
She will not have enough. She will only have $1480.
Step-by-step explanation:
The formula for simple interest is A=P(1+rt)
A=final amount
P=initial amount
r=interest rate per month
t=time in months
A=1000(1+(0.02)(24))=1480
Rachel will not have enough money after two years (24 months.)
Hope that helps!

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
A spinner with six section numbered from 1 to 6.
total number of times spins = 150
So, the number of times the number comes less than 5 is
= 150 x 1/5
= 150/5
= 30

Which is the equation of the line that passes through the points (4,3) and (6,2)?
A. Y= x - 1
B. Y= 0.5x - 1
C. Y= -0.5x + 5
D. Y= -0.5x + 1
Answer:
[tex] \large \boxed{y = - 0.5x + 5}[/tex]
Step-by-step explanation:
Goal
Find the equation of the line.Given
Coordinate points which are (4,3) and (6,2).Step 1
Find the slope by using slope formula or rise over run.[tex] \large{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
Substitute the coordinate points in
[tex]m = \frac{3 - 2}{4 - 6} \\ m = \frac{1}{ - 2} \\ m = - \frac{1}{2} \longrightarrow - 0.5 \\ m = - 0.5[/tex]
Step 2
Rewrite the equation in slope-intercept form by substituting m = -0.5[tex] \large{y = mx + b}[/tex]
Substitute m = -0.5
[tex]y = - 0.5x + b[/tex]
Step 3
Find the value of b by substituting any given coordinate points in the equation.Substituting both coordinate points still give the same answer.
Step 3.1
Substitute (4,3) in the equation.[tex]y = - 0.5x + b \\ 3 = - 0.5(4) + b \\ 3 = - 2.0 + b \\ 3 = - 2 + b \\ 3 + 2 = b \\ 5 = b[/tex]
Step 3.2
Substitute (6,2) in the equation.[tex]y = - 0.5 x+ b \\ 2 = - 0.5(6) + b \\ 2 = - 3.0 + b \\ 2 = - 3 + b \\ 2 + 3 = b \\ 5 = b[/tex]
Step 4
Rewrite the equation again by substituting the value of b.[tex]y = - 0.5x + b[/tex]
Substitute b = 5 in the equation.
[tex]y = - 0.5x + 5[/tex]
Hence, the equation is y = -0.5x + 5

1.) The length of a rectangle is 4 cm longer than the width. The
perimeter is 80 cm. Find the length and width. Write a system and
use substitution to solve.
Step-by-step explanation:
if a rectangle has 4 sides and there are two lengths and two widths
then we could split 80 by 2 and minus 4 from the length and then split that into two.
then your answer would be and 36 and 44
and the total answer would be half of each so the L=22 and L=22
and the W=18 and W= 18
sorry if this is wrong it least i tried :9
How would you express the area of the rectangle using the Distributive Property?
Answer:
C
Step-by-step explanation:
Step 1: Find your legth and width
Length = x + 5
Width = 3
Step 2: Use area formula to find area
l x w = A
(x + 5) x 3 = A
A = 3(x+5)
Step 3: Therefore Statement
Thereforethe answer to the question is C. 3(x+5)
Answer:
C. 3(x + 5)
Step-by-step explanation:
area of rectangle = length * width = width * length
A = area of largest rectangle
a1 = area of left rectangle
a2 = area of right triangle
The largest rectangle is made up of the the two smaller rectangles.
A = a1 + a2
Left rectangle: a1 = WL = 3x
Right rectangle: a2 = WL = 3 * 5
Total area of the two small rectangles:
A = a1 + a2 = 3x + 3 * 5
Apply the distributive property in reverse to 3x + 3 * 5 by factoring out a 3:
A = 3x + 3 * 5 = 3(x + 5)
The area of the largest rectangle is 3(x + 5)
We can also find an expression for the area of the largest rectangle directly by looking at its length and width.
The length of the largest rectangle is x + 5.
The width of the largest rectangle is 3.
A = WL
Substitute 3 for W, the width.
Substitute x + 5 for L, the length.
A = 3(x + 5)
Answer: C. 3(x + 5)

The longest side will be the hypotenuse
Hypotenuse² = 17² = 289
base² + altitude² = 15² + 8²
= 225 + 64
= 289 =Hypotenuse²
So, 8 m , 15 m , 17 m forms a right angled triangle
